Peptides, combination of peptides as targets and for use in immunotherapy against gallbladder cancer and cholangiocarcinoma and other cancers

Abstract

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

The invention claimed is: 
     
       1. A method for killing target cells in a patient who has gallbladder cancer and cholangiocarcinoma, comprising administering to the patient a population of activated T cells that kill a target cell that presents a peptide consisting of the amino acid sequence of SEQ ID NO: 3 on the cell surface. 
     
     
       2. The method of  claim 1 , wherein the T cells are autologous to the patient. 
     
     
       3. The method of  claim 1 , wherein the T cells are obtained from a healthy donor. 
     
     
       4. The method of  claim 1 , wherein the activated T cells are produced by contacting T cells with the peptide loaded human class I or II MHC molecules expressed on the surface of an antigen-presenting cell for a period of time sufficient to activate the T cells. 
     
     
       5. The method of  claim 1 , wherein the activated T cells are expanded in vitro. 
     
     
       6. The method of  claim 1 , wherein the peptide is in a complex with an MHC class I molecule. 
     
     
       7. The method of  claim 4 , wherein the antigen: presenting cell is infected with a recombinant virus expressing the peptide. 
     
     
       8. The method of  claim 7 , wherein the antigen presenting cell is a dendritic cell or a macrophage. 
     
     
       9. The method of  claim 5 , wherein the expansion is in the presence of an anti-CD28 antibody and IL-12. 
     
     
       10. The method of  claim 1 , wherein the population of activated T cells comprises CD8-positive cells. 
     
     
       11. The method of  claim 4 , wherein the contacting is in vitro. 
     
     
       12. The method of  claim 1 , wherein the population of activated T cells is administered in the form of a composition. 
     
     
       13. The method of  claim 12 , wherein the composition comprises an adjuvant. 
     
     
       14. The method of  claim 13 , wherein the adjuvant is selected from anti-CD40 antibody, imiquimod, resiquimod, GM-CSF, cyclophosphamide, sunitinib, bevacizumab, interferon-alpha, interferon-beta, CpG oligonucleotides and derivatives, poly-(I:C) and derivatives, RNA, sildenafil, particulate formulations with poly(lactide co-glycolide) (PLG), virosomes, interleukin (IL)-1, IL-2, IL-4, IL-7, IL-12, IL-13, IL-15, IL-21, and IL-23. 
     
     
       15. The method of  claim 14 , wherein the adjuvant comprises IL-2. 
     
     
       16. The method of  claim 14 , wherein the adjuvant comprises IL-7. 
     
     
       17. The method of  claim 14 , wherein the adjuvant comprises IL-15. 
     
     
       18. The method of  claim 14 , wherein the adjuvant comprises IL-21. 
     
     
       19. A method of treating a patient who has gallbladder cancer and cholangiocarcinoma, comprising administering to the patient a composition comprising a population of activated T cells, wherein the activated T cells kill cancer cells in the patient, wherein the cancer cells present a peptide consisting of the amino acid sequence of SEQ ID NO: 3. 
     
     
       20. The method of  claim 19 , wherein the T cells are autologous to the patient.
